Hallo, i have sainsmart LCD 2004, and it not working with my due. When i try the example code i get the following error at compiling:
\arduino\libraries\LiquidCrystal\FastIO.cpp: In function 'void fio_shiftOut1(fio_register, fio_bit, uint8_t, boolean)':
arduino\libraries\LiquidCrystal\FastIO.cpp:214: error: '_BV' was not declared in this scope.
With the I2CScanner i only get the info, no I2C device found.
what can be the problem ?
